To human eyes, the world at night is a formless canvas of grey. Many nocturnal animals, on the other hand, experience a rich and varied world, bursting with details, shapes, and colors. What is it, then, that separates moths from men? Anna Stöckl uncovers the science behind night vision.
Lesson by Anna Stöckl, animation by TED-Ed.
For camera guys-
Tarsier: Large aperture
Cats: Backlight
Frog: Slow shutter speed
Hawk Moths: High ISO
that's brilliant
Omg👍🏼😂
Omg nice :)
cool
cool
that picture of the human with tarsier eyes is nightmare fuel...
Lol it makes me think of Jonny Depp in Alice in wonderland
I know
its perfect
@@rebeccarakuza2845 me too
Too bad anime is popular
The lag is real with toads
Yea thats why they can't Minecraft PvP or be good at CS:GO
+Cydney Red idk man, could be a deadly sniper. Just a single changed pixel on the horizon and you're dead :p
0.25 Fps
Are you talking about mario toads OR real toads? (Mario toads are adorable )
yeah, low fps, but a 4K monitor for them would be like a old 190×120 would be for us.
Cats be in that avatar state
LOLOLOLOLOLOl
SOISOISOISOISOISOI
WOWWOOWOWOWO
Lmao!

toad eyes=internet explorer
What about mario toads?
what would internet explorer look like to a toad?
A long exposure camera more accurately
I like these Ted-Ed videos. This one is super interesting for some reason.
exactly... this one was awsm

I think the Animation is what makes it that much better.
+Nerd Nation Nice b8 m8
my eyes get really red at night.

Toad: "yo that bullet is coming straight at m-"
Bro this comment is hilarious but you’re a lil late
@@vixenkitty7942 I am latest!
I'll come back in a few weeks and I won't be... Probably
Joseph Bojarski and I thought I was later!
@@vixenkitty7942 now I am latest again >:)
The tarsier drawing was creepy as fuck
yeah and the way they brought it in was also really disturbing, it eats a moth and then slowly turns around and stares at us with red eyes while swallowing the moth, creepy af
How about the human with huge eyes? *shudders*
The night is dark and buzzing with insects
shwifty.
hannibus 42 You have now gotten shwifty right up in here
A man gotta get schwifty
So Rick is there Internet in space jail
actually thought on the possibility of human intellect in bug eyed organisms... then I remembered the universal police in RIck and Morty, the ones that jailed you in before I saw your pic
Can we appreciate how fluidly-continuous the animation was...!!! Great job animators...👍👍
More educational than school,wait,is there even such a word as educational? My school didn't thought me
This isn't Twitch.
They didn't teach you proper grammar either
TED-Ed will think you. Don't worry.
+Location lol
what
This is so well done that I had tears in my eyes near the end. I was emotionally moved! Longer exposure for the frog, and reflective cells for the cat, nature is so full of curiosities and these videos make them known. Thanks to everyone who made this.
Can we all appreciate how interesting the end lines of each and every TED-Ed video are? THEY MAKE YOU THINK 'wow... THAT was deep.'
They still can't see John cena
😂😂😂😂
True
Dead meme
Notorious Gentleman yea because you comment 2 years later
Mr. PewDieCat my comment was not an insult
Tarsier = large aperture
Tod = Long exposure
Moth = less pixel density hence large sensor size.
1:42 perfect character for a horror movie
One more interesting thing about eyes is they have evolved independently 50-100 times throughout the earths life.
Toad : Dude , did you see that?!
Other Toad : Gimme just 4 seconds buddy.
I like the eerie animation style.
“... the size of grapefruits...”
*PTSD has entered the chat*
2:12 -- Nikola Tesla believed we can do that too, he once thought we could see brain activity or project our thoughts using this technique, and maybe it could be the reason for how we sometimes "see" our imagination. it perhaps is more perceptive in cats because they have more visual neurons related with vision and projection! awesome!
So in ways an astronomer/photographer understands:
Tarsiers have bigger lenses = more photons
Toads have a slower shutter speed/longer exposure = collect more photons at the expense of image refresh rate
Moths have larger pixels = more photons per pixel
And cats have backlighting
1:42 Thank you, for the nightmare fuel.
So scary
Can Harambe see in the dark?
#dicksoutforharambe
omg can people stop with this meme
R.I.P Harambe 2016
im sorri
#Harambeisshit
+Frederik Andersen #AndSoAreYou
No. He's dead. Some idiots killed him.
It's so amazing!!! Thank you so much for sharing these great videos
2:10 she/he is good at drawing cats lol
i always love the end statement of each ted ed video
Would it be possible to undergo some kind of surgery to make human eyes like cat eyes?
it might take just a few millions of years to evolve, partially....
RIDDICK
If we can do that our eyes will glow
I was born with cat eyes.
Sarah Jangard FURRY
TED-Ed always knows how to make trivialistic stuffs interesting.
I would want cats eyes.
That hawk moth looked like an angry old man.
Who came here to see the cat?? Btw nice vid ted-ed...
I did. I have been interested in what they see recently.
what an animation.
.. hats off to the creativity👏👍👌
Amazing lesson Anna Stöckl. Truly Amazing.
For camera guys-
Tarsier: Large aperture
Cats: Backlight
Frog: Slow shutter speed
Hawk Moths: Pixel binning
1:25
I'm having nightmares....
I whouldn't mind to have cat eyes
You’ll see less colors though
@@Izakokomarixyz id take that sacrifice to see in the dark
Cats are colorblind
The narrator's voice is very clear. Good job.
1:40 how my classmates be looking at me when i open a bag of chips
I'm not sure why (maybe it was the detox or sleep deprivation) but at the end of basic training years ago I could suddenly see trees and people as white in the dark. It only happened once in my life, but it was amazing and gave me a huge advantage. Everyone else looked like toddlers stumbling around and tripping on something or nothing.
The usual darkness was a kind of purple btw.
interesting.
"what is it that separate moths from men?".... uh
Toad eyes have a lag of 4000ms. Let that sink in.
This video was awesome. One of my favorites. Illustration was spectacular too.
Don't know why but opening 3-4 sec music is Soo pleasent ❤️
They should do a follow up about those mirror cells. Try to really think about that. how does an cell made out of organic material reflect light so strongly?
I don't know really what's the correct answer, but it doesn't have to be organic. It could be crystals of a salt or something similar. I'll try to research it tho :D
Why do people even go to school? All they need is this channel
Am I the only one wanted a cat eye that can shine in the dark??
The art on this video is amazing
Thank you, cats, for inventing headlights for us.
but, how does this affects Harambe?!
dicks out for harambe
Lmfao
Pussy spread for Harambe
it doesnt affect harambe but harambe affects it.
It doesn't affect Harambe because he's dead
Therapist: Tarsierman isn't real. He can't hurt you.
Tarsierman: 1:41
And.... How can sharingan copy another skills?
Lek Vol'jin and how does byakugan see through things
Yeah but can science explain how Lelouch can control people?
This was great! Thanks!
It is amazing all the studying we humans have done.
I wouldn't want to have the moths eyes I'd probably freak out if I see everything shapeless.
Favorite animation thus far! Keep up with the awesome vids!!!
Thank you... Am learning more now than school.
Awesome video ! Thank you 💕
wayy more educational than I expected. I thought she was only gonna talk about the tapedum lucidum or however you spell it but I was very wrong. I actually learned things just now
Nature is absolutely incredible.
I don't get what the video is talking about, I can see in the dark.
Yeah you can see in the dark but not very well. Or at least not as well as nocturnal animals.
it was really intresting and i loved the animation. thanks for doing great job, ted-ed
Congrats on 3M subscribers! Also, very interesting video.
You tell me
Moths have disco balls on their heads XD
Not gonna lie the cat seems to do it the most efficiently because it doesn't sacrifice detail like the hawk moth and doesn't require extra size like the Tarsier. Also shining eyes?? That's so cool
I always wonder about animals who also spend time underground: pikas, marmots, prairie dogs, ferrets, et al.
This hawk moth at 3:14 looks like a damn Death Angel
I thought i could feel a moth flying in my brain. And people called me crazy
Having the cat eye mirror thing would so fucking cool
this is such a great series!
Moths are nocturnal yet they go crazy outside the kitchen window when I turn the light on during the night.
Don't forget most of this animals use all the sensors at once to accomplish their will and necessities : photo receptors, chemical receptors, high and low frequency receptors. Good information. 👍
3:03 imagine seeing the works at 4fps
I can see outlines as close family can also do
I learned that Misuzu Kamio is a nocturnal animal
XD we would be an anime character
Yay but not as good looking xD
+Bayonetta Is My Goddess but you like bayonetta
Well girls would.
+Bayonetta Is My Goddess True fact, they where actually secret lovers
The Loveless Bayonetta Lover What about manga??? Do you guys hate manga?????
Me:huh.. *turns off lights and easily finds a case of water*
it would be a pleasure to give content for a lesson to u guys !
how does an owl see? i love them.
owl eyes work like the tarsier's, they're front-facing and are very large for their body size. while they do see quite well, their main advantage is hearing. They have asymmetric ears that allow them to better pin point sounds. Also their round, slightly concave faces and face feathers help them to better focus sounds toward their ears, thus allowing them to hear the faintest sounds of their prey.
Thank you! ^-^
@@evergreen1326 oh yeah also they can't turn their eyes because they are tubes so that's why they also turn their heads A LOT
i already knew this, because my dad is a photographer explained ISO to me :)
big eye monkey explaination:
this is also why a DSLR takes better low light pictures than your smartphone, because more light falls on each pixel because the sensor surface area is larger :)
frog explaination:
the amount of light per pixel depends on the sensor (and therefor pixel) size and the photons that hit the sensor/pixel
that's why if you have a camera with manual controls, you can take photos in the dark that look good, but if the subject or the camera moves the image will be blurry.
Only true photographer will know.
+1 for correct usage of "adaptation"
What would happen if I went nocturnal, would I adapt to see better in the dark?
To reply to your end statement;
As a person with sleep issues, I do wake up when the world is sleeping.
This was a great episode.:D
Tarsier is available in our country known as Philippines
Just another great video :D
hi
1:41
What anime is this?
GREAT AS USUAL... ;)
Seems to me like we just found the new cast for Suicide Squad 2.
The tarsier, cat-woman, frogman, and butterfly-bitch. Bring back Deadshot and Harley Quinn, and we only need to find a villain.
Wow I Love how Cats see in the dark😃
Great video :)
1:30. Just putting this out there.
All hail the mighty chupacabra
I knew someone was gonna comment that momment xD creepy though
He looks like a little demon... Poor tarsier. . .
*John hiding in the dark, from deformed Garfield
"I can still see you John"
Nice video
the night is dark and full of terrors
So the Night Mode we used is using Toad mode
Most educational
